摘要:
Systems and methods for identifying alcohol content of a fuel in an engine. In one example approach, a method comprises adjusting fuel injection to the engine based on fuel alcohol content identified from crankshaft acceleration. For example, the crankshaft acceleration may be generated by modulating an air/fuel ratio in a selected cylinder across a range of air/fuel ratios while keeping the engine at stoichiometry.
摘要(中):
用于识别发动机中燃料的酒精含量的系统和方法。 在一个示例性方法中,一种方法包括基于从曲轴加速度识别的燃料酒精含量调节对发动机的燃料喷射。 例如,可以通过在保持发动机处于化学计量比的情况下在一定范围的空气/燃料比中调节所选气缸中的空气/燃料比来产生曲轴加速度。
